ChainCatcher 消息，据 CryptoSlate 报道，来自 USENIX Security 的研究人员公开披露了一项针对 Solana 历史证明（PoH）机制的时钟攻击漏洞，该漏洞早在 2025 年 12 月已私下告知 Solana 开发团队。研究显示，恶意调度领导者可通过“重新锚定”操控 PoH 逻辑时钟，使逻辑时间推进放缓，从而在物理时间内获得更长的交易选择窗口，并借助 TowerBFT 分叉选择机制孤立诚实领导者的区块，攻击者所需质押比例低于 33%。
Anza 旗下 5 万 SOL 奖金的 Alpenglow 安全竞赛已于 8 月 19 日截止，但由于竞赛规则将“仅在 Alpenglow 未激活时可触发的行为”排除在外，该漏洞未被纳入评审范围。Solana 开发团队表示已知晓相关行为，认为最严重场景在当前条件下发生概率较低，并预期 Alpenglow 升级可从根本上消除攻击前提。目前 Alpenglow 代码已包含于 Agave 4.2 客户端，但尚未在主网激活，预计随 Agave 4.3 正式上线。在此之前，该漏洞的过渡期风险仍未得到公开的实现层面分析与回应。
